Why aren't tags added to Yandex map?

Question

Yandex maps

Please tell me why the marks do not appear on the Yandex map, I did everything according to the example already working. But it doesn't work, the error "Uncaught TypeError: Cannot read property 'push' of undefined" hangs in the console.

What's wrong?

Answer 1

Set the variable mapsArryou are using as an array.
var mapsArr = [];
